Those of us who write online tend to have a very specific mental image of what the standard internet troll looks like. Their typical dwelling involves a wood-paneled basement, usually in the home of a parent. Their uniform is unwashed terry cloth, and their skin is the translucent white of a prehistoric deep sea fish. Less often considered, though, is where in the country they actually are.

Thanks to Wired, we now have some information on where in the U.S. troll populations are the densest. The magazine partnered with commenting platform Disqus to analyze 92 million comments over the course of 16 months, using an API programmed to identify and rate nasty comments. In this case, a toxic comment is defined as any that is rude, disrespectful, or unreasonable enough that it will prompt other users to leave a discussion. Once the API is fed the comments, it delivers a score from 0 to 1—anything above .9 or above is considered toxic.

Applying the API to over 2 million authors across more than 7,000 editorial platforms yielded interesting results. The south, for instance, is disproportionately inhabited by hostile trolls, but no state is as bad as Vermont, which has the highest output of bad comments at 12.2 percent. (You can click through to Wired to see the data visualized in map form.)

And what the hell is going on in Bellflower, California? Nestled in Los Angeles County just north of Long Beach, the city isn’t the meanest when it comes to terrible online commenters, but it does diverge most drastically from those around it—with a bad comment percentage of 32.7, Wired puts it at 335 percent more toxic than its neighbors. According to its census data, Bellflower’s racial makeup is roughly consistent with the areas that surround it, with white and Hispanic people making up the bulk of its residents. The two largest employers in the city are medical complexes—Bellflower Medical Center and Kaiser Permanente, which conjures some disturbing images of nurses and doctors tapping out hateful comments while their patients wither and die in the waiting rooms. (But not before writing some hateful comments of their own?)

But the most toxic city in the U.S. is Park Forest, Illinois. Park Forest is a middle-class suburb to the south of Chicago, and though it has a comment toxicity rating of 34 percent, 99 percent of the comments come from just two authors. Do they know each other? Are they married? Are they writing terrible comments to each other?

And finally, the data reveals that the most toxic time of day for internet trolls—the hour where the worst, darkest comments are made—is 3 a.m. No surprise there.
